MOTOR.

SPECIFICATION forming part of Letters Patent No. 380,557, dated April 3, 1888.

Application filed November 7, 1887. Serial So. 255,529. (No model.)

To aZZ whom it may concern.-

Be itknown that 1, WILLIAM J noon DUM,

of South Bloomfield, in the county of Pickaway and State of Ohio, have invented certain new and useful Improvements in Motors; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which- Figure 1 represents a front elevation of my improved motor for pumps. Fig. 2 is a top plan View of the same. Fig. 3 is an enlarged detail view of the pumpconnections.

This invention relates to improvements in motors designed for use on stock-farms for supplying water automatically from a well or cistern to the drinking-trough of the cattle.

The invention consists in certain novel combinations of devices for operating the pumprod and for automatically regulating the movements of said rod when in operation and for causing the stoppage of the working mechanism when the delivery or drinking trough is full, all of which will be clearly understood from the following description, together with the annexed drawings, and distinctly pointed out in the claims.

Referring to the drawings by letter, A designates a frame-work of any proper or convenient construction, which is erected by the side of the well from which water is to be supplied.

The frame A is preferably rectangular in plan, and between its upper horizontal side bars, a a, near one end thereof, is journaled a shaft, B. Upon shaft B, near its front end, but inside the frame A, is mounted a gearwheel, 0, which is provided with a small ratchet-wheel, D, on shaft B and engaged by a dog, 0, on the face of wheel 0, as shown. Upon shaft B, in rear of gear 0, is mounted acoilspring, E, the inner end of which is fixed to said shaft and the outer end secured to a crossbar, d, of frame A, as shown. By means of this spring E shaft B can be rotated, as is evident.

The rear end of shaft B may be extended beyond frame A for the reception of a second coil-spring, e, secured on said shaft and to an extended portion of bar cl, as shown. This spring 6 is preferably surrounded by a guardframe, 6, to prevent undue expansion of said spring or for supporting the extended end of shaft B. I propose in some instances employing cords and weights in place of the springs on shaft B, as may be found most advantageous. On the front end of shaft B, outside frame A, is keyed a pinion, b, which is engaged by a small pinion, Z), mounted on a shaft,f, suitably journaled on the frame A, the outer end of shaftf being squared for the engagement of a key or handle by which said shaft is rotated to wind the springs on shaft B, as is evident.

G designates a shaft parallel with shaft B, and similarly jonrnaled in the frame A to the inside thereof, and this shaft has keyed upon it a pinion, g, engaging gear 0 of shaft B and a gear, G, as shown.

H designates a shaft similar to shaft G and journaledparallelthercwith on frame A. Upon this shaft is mounted a gear, h, and a pinion, h, the latter being engaged by gear G, as shown.

I indicates an escapement-wheel on shaft H, controlled by the pendulum-dog i, which is mounted on a proper bracket-arm, i, secured to the side rail of the frame A, the pendulum rod 1 carrying a proper adjustable weight at its lower end, by which the rapidity of movement of the dog and escapement wheel is regulated.

J designates a shaft having hearings in frame A on the side opposite shaft B, but below the plane of the same, this shaft being provided with a pinion, j, engaging the gear h of shaft H. The front end of shaft J is extended outside frame A, and has a crank, preferably formed by a crank-disk, J, provided with a wrist-pin, j.

K designates a walking-beam pivoted to the upper front rail of frame A, or to suitable supports thereon, the longer arm of said beam being connected by a pitman-rod, 70, with the wrist-pin j of disk J, so that said beam is oscillated upon the rotation of the disk. The shorter arm of beam K is connected with the plunger-rod of a pump, L, by means of a pitman, K, as shown, so that the oscillation of beam K causes the reciprocation of the plunger in pump L, as is evident,

M designates a tank or water-trough placed by the side of frame A and adapted to receive the water from pump L.

N designates a cranked rod jonrnaled in frame A at one end and having its bent arm extending over tank M, as shown. Rod N is situated below shaft J, its bent portion lying beneath disk J thereon. On the outer end of rod N and resting in the tank M is secured a float, O.

N designates an upstanding arm or projection secured to the bent portion of rod N below disk J, and having its upper end, 11., bent as shown. WVhen in operation, motion is transmitted from shaft B, through the gearing and shafts, to disk J, and through the latter to the walking-beam and pump-piston, as described. The water as it fills tank M raises the float O, and with it rod N and its attached arm N. Before the tank fills to overflowing arm N has been elevated sufficiently to cross the path of movement of wrist-pinj on disk J, its curved portion n preventing injury to either wrist-pin or arm, as the wrist-pin will slide over such curved portion, depressing the float until the same has risen sufficiently to cause the arm N to effectually bar the movement ofthe wrist-pin, thus stopping the pump and motor until the Water in the tank has diminished sufficiently to allow the float to descend and disengage arm N and wrist-pin j.

It will be observed that the pendulum and escapement controlling the rotation of shaft H produce a uniform movement of the beam K whether the tension of the spring E e be full or relaxed.

Upon the descent of the float the motor will instantly resume its work of pumping until the tank M be again filled, so that no attention is required by the motor expert to keep it wound up.

Having described my invention, I claim 1. The apparatus comprising frame A, carrying shaft B, the shafts G, H, and J, driven from shaft B, the escapement-wheel I on shaft H, and the pendulum-dog z, engagingthe same, with the crank-disk J on shaft J, its wristpin j, the walking-beam K, pivoted above the same and connected at one end to wrist-pin j by a pitman and at the other end to the pumppitman, and the float 0, rod N, and its arm N, all constructed and arranged to operate substantially as and for the purpose described.

2. The apparatus comprising frame A, shafts B, G, H, and J, mounted thereon, springs E e, actuating shaft B, and gearing between said shafts, with the escapement-wheel I, dog i, and weighted adjustable pendulum I, the crankdisk 'J, its pin j, walking-beam K, the rods connecting it with wrist-pin and pump pitman, and the cranked rod N, its arm N, and its operating-float 0, all constructed and arranged to operate substantially in the man ner and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

WVILLIAM JACOB DUM.
